Ultrasonography was used to examine 42 patients who were complaining of popliteal and suprapatellar pain. When clinically indicated, patients also underwent phlebography, arthrography, and posterior synovectomy. In 17 patients, Baker's cysts were demonstrated by ultrasonogram. Of these 17 patients, four had confirmation of the cysts by arthrography. One patient had simultaneous deep venous thrombosis, proved by phlebography and arthrography. Five patients underwent posterior synovectomy, and the surgical specimens closely correlated with the dimensions predicted by ultrasonography. Internal echoes within the cysts correlated at surgery with either necrotic debris or organized hematoma. To our knowledge, this study is the first series where surgical correlations have been made with the ultrasonographic observations. Ultrasonography of the knee and surrounding area is a useful, painless, and relatively inexpensive method, with several advantages over arthrography.
超声检查用于检查42例主诉腘窝和髌上疼痛的患者。根据临床指征，患者还接受了静脉造影、关节造影和后滑膜切除术。17例患者的超声检查显示有贝克囊肿。在这17例患者中，4例经关节造影证实有囊肿。1例患者同时患有深静脉血栓形成，经静脉造影和关节造影证实。5例患者接受了后滑膜切除术，手术标本与超声预测的尺寸密切相关。囊肿内的内部回声在手术中与坏死碎片或机化血肿相关。据我们所知，本研究是首个将手术结果与超声观察结果进行关联的系列研究。膝关节及周围区域的超声检查是一种有用、无痛且相对便宜的方法，与关节造影相比有几个优点。
